Hi,
I have a Canon XL1-S camcorder with a CA-910B mains charger (this is the charger that comes with the camera as default). I'd like to convert the charger so I can power it from car battery.
I've taken the lid off the charger. I think I can connect an 8.45volt DC source across the smoothing capacitor after the transformer and rectifier diodes. Does this sound sensible? I figure that all I need to do is build a regulator circuit that will produce 8.45v from 12v and pump this into the charger over the capacitor (C22)..
However, I'm not very experienced at these things and I'd be enormously thankful if you geniuses (or genii?) could have a look at the PCB. I've scanned it...
The large images are LARGE (400 kbytes). I've flipped the top side so it matches up with the track side
LARGE images
SMALLER images (for those with slow internet connections)
Many many thanks, Jack
